Influence of gradually vacating hexagonal patterns composition of C[sbnd]C bond in TWCNTs molecular structure using the FE method for vibrational analysis

Abstract

The authors use the FE research to analyse and predict the oscillational performance of TWCNTs (Triple-Walled Carbone Nanotubes) in this work. Different types of nanotubes like chiral, zigzag, and armchair as well as different lengths and diameters are used for analysis purpose. The novelty is authors included the chiral structure which is difficult to model for simulation purpose. The approach employed here to account for the variation in length in atomic models produced by removing hexagonal patterns has either never been utilised or has very little evidence. As a result, this technique's use is distinct and novel. Moreover, the authors investigate the effect of gradually removing the hexagonal patterns which contain the Carbon-Carbon(CC) bond ring in triple-walled carbon nanotube models. Molecular structural mechanics methodology is used for developing and simulations of armchair, zigzag and chiral triple walled carbon nanotube (TWCNTs). The process of removing the Carbon-Carbon bond ring from the outside wall of TWCNTs by maintaining the inside walled unchanged. Authors analysed the resonant frequencies for different attached masses ranging from 10−16to 10−23gm on TWCNTs and different boundary conditions for TWCNTs.
